more obstack cleaning up

[Geoffrey Keating <geoffk at romulus dot sfbay dot redhat dot com>]

You'll never believe this, but there are actually places in GCC that
include obstack.h and yet don't actually use obstacks any more!

And, there are some bogus comments that refer to obstacks!

Bootstrapped on x86-linux.
